Congrats to you both Darren & Tina.
Best of luck getting a sleeping pattern happening before next season!
INMHO play classical/mellow/acoustic music to Summer when she is feeding (everytime, bottle or booba - doesn't matter) and she is in her nice comfort zone.
Then play this
same music when it is nighty night time, they think "ahhh my happy place, time for a big fart and a nice sleep"



. Worked a treat with both my squids and a couple of friends who have tried it too. Put it on repeat all night (low volume) and they tend to go back to sleep easier after waking too.
